Summary (written by the submitters)
Sensory experience refines neural circuits during critical periods of postnatal development. Although neuronal activity is known to orchestrate the circuit wiring that underlies this process, the environmental cues that restrain developmental plasticity as animals mature are less clear. Here, we examine the experience-dependent maturation of the mouse primary visual cortex (V1) across postnatal development using paired single-cell transcriptomic and chromatin accessibility sequencing.

In addition to identifying the activity-dependent gene programs that emerge within each cortical cell type, we find that light exposure drives astrocyte maturation through cell type-specific recruitment of the glucocorticoid receptor (Nr3c1/GR) to chromatin. Astrocyte GR signaling activates an extensive gene regulatory program that is partially conserved in human brain development and promotes maturation processes that may trigger critical period closure. Collectively, these findings reveal that astrocyte GR signaling restricts neuronal plasticity. ​​Glucocorticoid regulation of astrocyte maturation may also contribute to the effects of early-life stress across the brain, and the disruption of this process may increase susceptibility to neuropsychiatric disease.

Download · which file do I need?

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE306261_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1310311 and SRA study SRP612457. Searching any of these in the dataset finder brings you back here.
